Single Rope Mechanical Bucket-Single Rope Grab Bucket
Single Rope Grab Bucket
Single rope grab is applicable to only a lifting drum(single hook) of all kinds to crane, the open and close institutions is novel, it is free to open or close for load and unload materials, the whole machine is easy to operate and it can be used for underwater and ground operations for material grabbing and transfers.
Note: this grab bucket cannot open in the sky , the hand type and remote control type can realize open in the air.
Single Rope Grab Working Principle
Single rope grab bucket opening and closing is mainly elastic elements car-riage and lock with exercise etc. During grabing materials , the open grab will fall upon materials, the steelcable drios to make sliding mechanism slide down, due to the effect od springs mechanism, the grab fouches the hook , then the driver lifts the sliding mechanism to lift lower separator or above ground , the steel cable drops to make the sliding mechanism fall for a distance, and pressure on grab from hook will disapper, due to the effect of spring on head, the grab will tum to go off hook, the driver re-lifts and the jaw will open due to effects of lower separator and material dead load.
